Mrk 205 in Draco .... who is right?

Dear Friends,

One of the most celebrated quasars is Markarian 205, a fairly bright
quasar in Draco (mag 15.24), which has led to an interesting controversy
the past few years as to whether it is related to NGC 4319 in the
immediate vicinity or not. The dramatic difference between the redshifts
of these two "players" (z=0.07 vs z=0.006) has led to conflicting
interpretations of the redshift and whether it can be used as an
indicator of distance or not.

For an image based on 30 minutes total exposure, I kindly direct you to

Clear skies!
